exynos5420: Set SPLL to 400MHz
Increase SPLL to 400MHz from 300MHz as we set SPLL as the switching parent for ARM and KFC. This value is as per recommendation of the hardware team. This is ported from https://gerrit.chromium.org/gerrit/62618 Signed-off-by: David Hendricks <dhendrix@chromium.org> Change-Id: I8a5a5b957083b0b1f3e3e318fe5753cf7ae19223 Reviewed-on: https://gerrit.chromium.org/gerrit/65432 Reviewed-by: Gabe Black <gabeblack@chromium.org> Tested-by: David Hendricks <dhendrix@chromium.org> Commit-Queue: Gabe Black <gabeblack@chromium.org> Reviewed-on: http://review.coreboot.org/4464 Tested-by: build bot (Jenkins) Reviewed-by: Patrick Georgi <patrick@georgi-clan.de>
